Spare a thought for the junior/mid-level devs who don't understand clever patterns, and the seniors who haven't read the same blog posts as the implementor of the switch(true).

Completely agree, it's like writing readable prose, understand your audience.

That said, give me proper pattern matching in JS. Hard to live with languages that haven't caught up yet.

I really want this. Along with switch being as expression. Seems like something that JavaScript is obviously missing.

Even PHP has this now, albeit with a different keyword (match) due to existing switch semantics being pretty bad

Unfortunately JavaScript still hasn't caught up with CoffeeScript.

Of course, you can't evaluate prose in a REPL and see for yourself what it does.

I agree that overly clever code is always to be avoided. But is this really overly clever? I wouldn't expect an engineer early in their career necessarily to understand on sight what it does. But I might worry a little for one who couldn't figure it out through experiment.
